Body Filler for concrete voids

[/pine]

I have thickened epoxy with Cabosil/Aerosil (fumed silica, which is probably not good to breath) along with micro balloons, milled glass fibers, and even pink fiberglass house insulation. All in "marine"use.

Haven't tried it myself, but some are using graphite on boat bottoms.

I love the newer fillers...micro-spheres (once called Q-cells) etc... light and easy to sand...Cabosil is much harder/durable but also harder to sand...
Is the graphite like carbon fiber? (same thing?) I know they say graphite on things like fishing rods and golf club shafts etc...

It is not structural, like graphite fabrics. Its a powder, and mainly intended to reduce abrasion.
